Answer:

90 people

Step-by-step explanation:

Total: $775

DJ: $250

Cake: $75

Unknown party guests each getting $5

Let the unknown be x

We can form an equation; <em>DJ + Cake + x number of party guests = $775</em>

<em>250 + 75 + 5x = 775</em>

<em>325 + 5x = 775</em>

Subtract 325 from <u>both sides of the equals sign</u>.

<em>5x = 450</em>

Make <em>x</em> the subject and divide both sides by 5

<em>x = 90</em>

There were 90 party guests.
